12. Why do scientists study extreme environments and the creatures that live in them? Discuss the following: A suggested answer Scientists study extreme environments and the creatures that live in them to help us understand how life might exist on other planets and what it takes for a world to be habitable. _________________________________________________________________________________________________________________________________________________________ Ministry of Education - Second Semester 2021-2022 Grade 8 – Unit 5 – Life in the Extreme – Lesson 1 (Vocabulary)

( ) People living in the Arctic have given polar bears different names. ( ) Listen, then read the following paragraph about polar bears and answer the questions given. In the Arctic, the temperatures are very harsh as they can go as low as -40° or -46° C in winter and stay that way for days or weeks, but polar bears can handle these conditions and thrive there as their bodies have adapt ed by having two layers of fur that prevent almost all heat loss. In fact, the fur keeps them so warm that adult males can quickly overheat when they run. Polar bears are also tall, as a typical adult bear may reach over 3 meters when standing on its hind legs. Throughout the Arctic, polar bears are known by a  variety  of common names, including Nanook, ice bear, sea bear, Isbjorn , and white bear. Nowadays, warmer summers in the Arctic have caused a lack of sea ice, which is making it more difficult for polar bears to find food. Click to listen Put (T) for True and (F) for False.

16. Discuss: Work in pairs: (Note you can do it independently as well) How can studying harsh environments like the desert and camels that live there help our community? Studying harsh environments, like the desert and the camels that live there, can help us adopt new ways to conserve water and find innovative ways to handle heat. The study would focus on understanding a variety of elements of the desert and observing camels habitats. *Put a (  ) if you followed the criteria.

17. You decide: Choose an activity. 1- Work independently: Write a paragraph about how the study of extremophiles could help us to discover life on other planets . 2- Work in pairs: (Note you can do it independently) Will human activities eventually turn the whole Earth into a harsh and an extreme environment? Why or why not? Discuss and share your response with the class. 3- Work in groups: (Note you can do it independently) Conduct a survey to find out what other students think about the possibility of life on other planets. Summarise what you learn for the class.

18. Work independently: Write a paragraph about how the study of extremophiles could help us to discover life on other planets. Possible answers The study of extremophiles could help scientists understand how life might exist on other planets with harsh environments that are similar to the ones on Earth. Studying these conditions could also help us adapt and make our world more habitable. _________________________________________________________________________________________________________________________________________________________ Ministry of Education - Second Semester 2021-2022 Grade 8 – Unit 5 – Life in the Extreme – Lesson 1 (Vocabulary) You decide:

19. In my opinion, human activities will not eventually turn the whole Earth into a harsh and an extreme environment but would typically cause some climate change for a variety of reasons. The pollution caused by factories and increasing plastic waste are a few conditions that may lead to climate change. We should start planting trees in place of the trees we are cutting, to help produce fresh air. We can also adapt to use less plastic and recycle as much as possible. 2.

These conditions are similar to parts of Earth, where life exists. This could also mean that life can exist on other planets with similar extreme environments.
